There is some bad news, Game of Thrones fans! The final season of HBO series has already been delayed, and now the last remaining hope for the fans was author George RR Martin's Winds of Winter. The author was supposed to release the next book in his A Song of Ice and Fire saga, Winds of Winter at the end of 2018, but fans will now have to wait for some more time.

"No, winter is not coming... not in 2018, at least. You're going to have to keep waiting for THE WINDS OF WINTER. ... I do want to stress...indeed, I want to shout... that FIRE & BLOOD is not a novel," Martin said in a statement.

"This is not a traditional narrative and was never intended to be...let's call this one 'imaginary history' instead. The essential point being the 'history' part. I love reading popular histories myself, and that's what I was aiming for here... As for me, I'm returning once again to THE WINDS OF WINTER."

In Martin's words, Fire and Blood "covers all the Targaryen kings from Aegon I (the Conquerer) to the regency of Aegon III (the Dragonbane)."

GoT fans, who have been waiting for last seven years for Winds of Winter, were disappointed after the news came. Some even took to Twitter to react on the issue.
